I have a 2008 Toyota Yaris S Sedan. I’ve had it for 5 years, and it currently has 63,000 miles. About 3 years ago, it started stalling out while I was driving. It was only occasional, but it soon got worse and more frequent.
First problem: It would stall out when I would drive 35 MPH or under when it was 20 degrees or colder or when parked in direct sun. It would stall while driving and after I stopped or in Park
Second Problem: It would stall out when I would drive 70 MPH or under, while driving, no matter the weather conditions.
Third Problem: On cruise control, the car would loose speed and drop down to 50 MPH then leap forward and speed up to 90-95 MPH before settling back on 73 MPH.
Fourth Problem: It jerks while driving. It’ll start to stall, then speed up, then start to stall, then speed up, repeat once more then speed up.
Fifth Problem: When the first three problems occurred, the car would shake during and after.
I’ve taken the car in seven times to two different Toyota dealerships, with nothing found. They were able to recreate the stalling issue, but none of the others. I contacted the Toyota company and they opened an inquiry, but found nothing and closed the case. I need this car to last me a couple more years.
Any ideas as to what the problem could be and if it’s fixable?
